Abstract:
Background: Open reposition and rigid internal fixation are the main methods of treatment for traumatic injuries of the facial skull and an important stage of bone-plastic, reconstructive, and orthognathic surgery. In contemporary maxillofacial surgery, fixators, implants, and endoprostheses made of titanium or its alloys are widely used due to the high corrosion resistance and biocompatibility. However, recent studies have shown that none of the metal implants used in maxillofacial surgery, orthopedics or traumatology is completely inert. Moreover, they always interact with the surrounding bi

Abstract:
It is known that complex growth environments often induce inhomogeneity in two-dimensional (2D) materials and significantly restrict their applications. In this paper, we proposed an efficient method to analyze the inhomogeneity of 2D materials by combination of Raman spectroscopy and unsupervised k-means clustering analysis. Taking advantage of k-means analysis, it can provide not only the characteristic Raman spectrum for each cluster but also the cluster spatial maps. It has been demonstrated that inhomogeneities and their spatial distributions are simultaneously revealed in all CVD-grown M

Abstract:
Detection of ferromagnetic resonance (FMR) by photothermal beam deflection has been used to study the spatial inhomogeneity of magnetic properties. The technique has been applied to measure the depth dependence of FMR in layered recorder tapes and to determine the lateral variation of the demagnetizing field in metal–glass ribbons.

Abstract:
Abstract With the wide application of additive manufacturing components and composite materials, it is of great significance to detect defects with non-destructive testing methods in the material manufacturing process and in service. Due to the strong attenuation and inhomogeneity characteristics, it is inefficient and poor imaging results to detect its internal defects by conventional ultrasonic testing methods. To improve the detection accuracy, this paper proposes an improved imaging algorithm with time reversal-total focusing method (TR-TFM) imaging technology to improve the defects detect

Abstract:
This paper discusses the experimental examination of anisotropic steel-made samples subjected to a static stress load. A nondestructive testing (NDT) measurement system with a transducer, which enables observation of local hysteresis loops and detection of samples’ inhomogeneity, is proposed. Local hysteresis loops are measured on two perpendicular axes, including one parallel to the rolling direction of the samples. The results confirm that the selected features of the local hysteresis loops provide important information about the conditions of ferromagnetic materials. Furthermore, it is show

Abstract:
In the paper, a stress-strain detection method is used by correlation point interferometry, in which the resolution of the recording surface changes has been significantly (ten times) improved. This result was obtained by applying a different image-processing algorithm, which allows the recording of 3D surface changes in on-line mode. The deformation wave that occurs during heating propagates through the entire sample and interacts with the interfaces. The inhomogeneity and residual deformations of a material lead to a distortion of the front. The speckle electron interferometry (ESI) method a

The IC device surfaces are often protected by silicon oxide and silicon nitride layers. Therefore, these insulation layers also cover any inhomogeneity

Abstract:
ABSTRACT A promising progenitor scenario for Type Ia supernovae (SNeIa) is the thermonuclear detonation of a white dwarf in a close binary system with another white dwarf. After the primary star explodes, the surviving donor can be spontaneously released as a hypervelocity runaway. One such runaway donor candidate is LP 398-9, whose orbital trajectory traces back ≈105 yr to a known supernova remnant. Here, we report the discovery of carbon-rich circumstellar material around LP 398-9, revealed by a strong infrared excess and analysed with follow-up spectroscopy. The circumstellar material is mo

Abstract:
Inverse problems are very challenging as these problems involve, finding the cause by analyzing the effects. In structural dynamics problems, the effects are normally measured in terms of dynamic responses in structures. These responses which are used to find the cause generally have partial data, embedded with measurement noise, and are truncated. Due to these problems, inverse problems are generally ill-posed in most cases as against forward problems. In this dissertation, we solve five different types of inverse problems involving high-frequency transient loads. All these problems are sol

Abstract:
In this work, a novel approach is proposed that would be able to rapidly diagnose the presence and location of inhomogeneity in turbid media. In this approach, ultrafast pulse laser is used as a detecting source and the time-resolved backscattered light signals are collected around the boundary of the target. The log slopes in the decaying log tail of the detected signals will be analyzed and used for the detection and image of embedded inhomogeneity. The relatively high absorption in the foreign object will result in a steeper log slope when the detector is located close to the object. A slim

We describe and analyze a system comprising a confocal scanning system, a coherent spatial filtering system, followed by detection, and then a second spatial filtering system. In this method, an object is embedded in an inhomogeneity, in particular, a diffusing material. A point source of light scans across the front surface of the diffuser. Transmitted light illuminates the object, embedded within the diffuser. The light emerging from the diffuser is imaged onto a detector, in front of which is a slit that moves in synchronism with the illuminating beam, or alternatively, the inhomogeneity ob

Abstract:
The paper presents measurements of resistivity changes in homogeneous medium (water–saturated sand) with spherical inhomogeneity made from the substance of sulfide waste from gold mining (Talmovka dump, Kemerovo region) performed in a laboratory. Repeated resistivity measurements over single profile in time domain show the process of pore solution spreading (diffusion) from the waste material to the water–saturated sand and its further neutralization. The time–varying resistivity data is processed in Res2Dinvx64 program with a time–lapse survey option.
